Thread, thread stack, method stack, the difference of creating thread

1. A thread is actually a stack , Each thread has a name , For example, the main thread is called main Threads , But the name of the thread has nothing to do with the method stack in the thread

2. How to create threads （ Take the main thread as an example ）
First allocate a stack space , And then press the stack （ Each thread is created , There will be a main method stack , That is, speaking of code, there must be a method stack ）, This method stack is actually the same as our ordinary calling methods , They all come from the methods of classes and objects
With main Thread as an example ,jvm Distribute Main thread space , call Object's main Method ,main Method stack …, and main Resources available by methods , Now only main The object of the method attribute

Again , We create threads , First of all, there must be a class , object （ Realized runnable Interface ）, Then call the api , here jvm Allocate a stack space , Push the , Of this object run Method stack , And this run Methods also come from objects , At the moment run Method You can only get Of this object attribute

To make a long story short , Everything is class and , object , Threads are stack space , In stack space Stack frame is method stack , These stack pressing processes , It's all called Class , So in the method stack Properties and methods that can be called , Can also be applied to Of classes and objects The rules
